maxon motor Equipment We Repair — By Category
maxon motor Product Lines We Repair
Our engineers are trained on the full maxon motor product range. Below are the major product families we service.
EC-45 Brushless Motors
Compact brushless DC motors (45 mm diameter) widely used in surgical robots, precision automation, and compact industrial equipment. Common failures include stator winding insulation breakdown, hall sensor faults, and commutation errors under high thermal stress.
EC-90 High-Power Motors
Heavy-duty brushless servo motors (90 mm frame) for automotive test rigs, CNC spindles, and industrial robotics in Indian plants. Frequent repair issues include bearing wear, rotor imbalance, encoder signal loss, and firmware corruption in integrated drive electronics.
Planetary Gearbox Modules
Precision single and multi-stage planetary reducers (1:3 to 1:1000) integrated with maxon motors for torque multiplication in medical devices, industrial automation, and defence applications. Typical repairs address gear tooth fracture, bearing preload loss, and output shaft runout.
Integrated Motor Controller Modules
Maxon DEC and custom servo drive modules combining motor control logic, encoder feedback, and CAN/RS485 communication. Common failures include capacitor dry-out, FET thermal shutdown, encoder interface corruption, and firmware version incompatibility with host systems.
Maxon Speed Reducers and Transmissions
Spur and planetary transmissions for precision load distribution in Indian manufacturing equipment, food processing automation, and textile machinery. Repair demands focus on shaft seal leakage, internal lubrication starvation, and gear mesh alignment after extended operation.
Encoder and Feedback Systems
Absolute and incremental encoders integrated into maxon motor shafts for closed-loop servo control in robotic and positioning applications. Failures include connector oxidation, bearing runout causing signal jitter, and firmware address conflicts in networked systems.

Common maxon motor Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in maxon motor equipment arriving at our workshop.
- ✓Stator winding insulation failure and phase-to-ground short — Thermal cycling stress in high-ambient Indian industrial environments and inadequate thermal management in compact EC-45/EC-90 housings causes polyimide insulation to micro-crack, allowing moisture and conductive particles to bridge phases and ground. Operating beyond thermal limits in textile mills and foundries accelerates this failure.
- ✓Hall sensor signal loss or inconsistent commutation — Maxon motor hall sensors mounted on the stator interior experience solder joint fatigue under vibration (common in Indian CNC and automation equipment), or rare-earth magnet demagnetization from thermal overshoot beyond 150°C nominal, causing sensor signal dropout or jitter at specific rotor positions.
- ✓Planetary gearbox gear tooth fracture and spalling — Sustained shock loads in Indian automotive test benches, punch press automation, and industrial robots exceed maxon gearbox torque ratings; combined with inadequate lubrication intervals and contamination (metallic particles from bearing wear) causes progressive pitting and eventual tooth shear at load-bearing flanks.
- ✓Encoder signal dropout and position feedback loss — Maxon integrated encoders (EPOS, MR-256 series) suffer connector corrosion in humid Indian coastal and food-processing environments, or bearing runout causes signal signal-line capacitive coupling loss. Firmware version mismatch in CAN-bus networked systems also causes periodic address conflicts.
- ✓Motor overheating and thermal shutdown under sustained load — Inadequate heatsinking, bearing friction increase from wear, or dust/fibre accumulation on motor housing (common in Indian textile mills and plastic extrusion plants) reduces convective cooling. Winding insulation also degrades incrementally, raising resistive losses that compound heat generation.
- ✓Rotor imbalance and vibration after gearbox replacement — Misaligned rotor installation or shaft runout exceeding 0.1 mm during planetary gearbox re-assembly introduces unbalanced mass distribution. In Indian precision CNC spindle and robotics applications, even 0.5 gram imbalance at 3000+ RPM generates harmful vibration and premature bearing wear.

Frequently Asked Questions — maxon motor Repairs
Do you repair maxon motor equipment anywhere in India?+
Yes. Synchronics repairs the full maxon motor product range — brushless DC servo motors, planetary gearboxes, integrated motor controllers, encoders, and custom OEM modules. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Vadodara, and all other major cities. All repairs are handled at our main facility in Vadodara, Gujarat, with 180+ engineers and full test capability.
What maxon motor series do you most commonly repair in Indian industries?+
The EC-45 and EC-90 brushless motor families are most frequent — used extensively in Indian automotive test benches, medical device assembly, and industrial robotics. We also repair many maxon planetary gearbox modules (GP-22 through GP-62 series) integrated into CNC and precision automation equipment. DEC motor controller modules and EPOS encoder systems are also routine repairs across Indian defence and aerospace OEMs.
My maxon motor EC-90 shows commutation errors and the servo behaves erratically. What is the fault?+
Commutation errors in EC-90 motors are typically caused by failing hall sensors, stator winding insulation breakdown, or firmware corruption in integrated drive electronics. Synchronics uses oscilloscope-based hall signal capture during motor spin-up to isolate the fault, then performs winding insulation tests, hall sensor resistance/timing checks, and drive module firmware re-flashing if needed. We bench-test the repaired motor under closed-loop servo load before return.
How long does a maxon motor repair typically take?+
Diagnostic and straightforward repairs (connector replacement, encoder re-alignment, firmware update) typically complete within 5-7 business days. Complex repairs requiring stator rewinding, gearbox disassembly, or custom bearing re-balancing take 10-15 business days depending on spare parts availability. Synchronics prioritizes urgent defence and aerospace repairs with expedited turnaround. Estimates are provided within 48 hours of intake.
Do you offer warranty and post-repair support for maxon motor repairs?+
Yes. All Synchronics repairs carry a 12-month workmanship warranty covering parts and labour. We provide detailed post-repair technical documentation including test reports, calibration certificates, and any firmware version updates applied. For critical Indian manufacturing and defence customers, we offer extended warranty and field support through our partner network across major industrial hubs.
How do I send my maxon motor unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a maxon motor drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on maxon motor repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your maxon motor unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
